New Developments & Detailed Microstructural Characterization of AHSS
The continuous demand by the agricultural and heavy transportation consumer industries for stronger, tougher, lighter and more cost-effective steel products represents a series of unique opportunities and challenges for the steel industry. To face these, it is necessary to have a fundamental understanding of the intrinsic relationships between alloy design, thermomechanical processing, transformation behavior, final microstructure and mechanical properties. This work presents an example from conception to validation. The fundamental concept was based on information from different thermodynamic software packages and mean flow stress (MFS) models applied to the designed steel compositions, TMP and transformation behavior. The final microstructure was characterized using electron optics techniques (OM, SEM-OIM-EBSD and HRTEM). The results of this study will be presented and discussed.
